StackEvolve · Legacy Modernization

Kill your tech debt. Ship faster.

Legacy maintenance eats 60–80% of IT budgets. We migrate PHP, Java, and .NET codebases to modern, maintainable stacks — incrementally, with no big-bang risk.

Migration paths

From dead-end stacks to hireable ones

These are the moves clients pay for most. Each is done module-by-module, never a risky big-bang rewrite.

FAQ

Common questions

We always start with a paid Assessment phase. Legacy code hides surprises — the audit surfaces them before we quote the build, so the implementation contract is fixed-scope with a contingency buffer.
